[GNC] Simultaneous access

[Ken Farley]

No.

Using an SQL database just means you are deciding where you are going to 
save your data. The way the program works is that it loads your data 
file into memory and any changes you make are done in memory. Data is 
not saved anywhere until you specifically write it to wherever you store 
it. There's no multiple access, no simultaneous updating. If someone 
else loads the same datafile into memory, whatever changes either user 
makes, the file that becomes the permanent data file is the one written 
last.
